To connect to BlackBaud Raiser's Edge NXT, you can use either a DSN or an ODBC connection string. Both of these methods use the Database's Open method.

Connect to a DSN

To connect using a DSN:

var db = new Database();
db.open("DSN=CData RaiserEdgeNXT Sys", (err) => {
    // Use the connection
});

Provide a Driver Connection String

To connect using an ODBC connection string:

var db = new Database();
db.open("DRIVER={CData ODBC Driver for Blackbaud Raisers Edge NXT};SubscriptionKey=MySubscriptionKey;OAuthClientId=MyOAuthClientId;OAuthClientSecret=MyOAuthClientSecret;CallbackURL=http://localhost:33333;;", (err) => {
    // Use the connection
});
